ZrPped up! Oxazolidinones are synthesized by treating glycerol carbonate or glycerol with urea in the presence of γ-Zr phosphate as the catalyst. Increasing the temperature increases the conversion yield, but the selectivity decreases, making the separation process more difficult. Two isomers, 6 and 6′, are formed from glycerol carbonate with a quasi-molar ratio, whereas the formation of 6′ is preferred when starting from glycerol.
